(Consumer Confidence Report)
This report is intended to provide you with important information about your drinking water and the efforts made to provide safe drinking water.

What is the source of my water?
The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and groundwater wells. As
water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material,
and can pickup substances resulting from the presence of animals or from human activity.
Ground Water - Well
The Department of Natural Resources conducted an assessment of our source water to determine its susceptibility to contamination. The
assessment is a three-step process of identifying an area around our wellhead(s), inventorying potential sources of contaminants within that area (a
one-half mile radius around the wellhead(s)) and a look at the adequacy of well construction. The assessment can be used to develop a wellhead
protection program to protect this valuable resource. If you want to know more about the assessment or wish to participate on a watershed protection
team to protect this valuable resource, then please call 573-431-2280.
Why are there contaminants in my water?
Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of
contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be
obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline (800-426-4791).
Contaminants that may be present in source water include:
A. Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock
operations, and wildlife.
B. Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban stormwater runoff, industrial, or domestic
wastewater discharges, oil and gas production, mining, or farming.
C. Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses.
D. Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum
production, and can also come from gas stations, urban stormwater runoff, and septic systems.
E. Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining activities.
In order to ensure that tap water is safe to drink, the Department of Natural Resources prescribes regulations which limit the amount of certain
contaminants in water provided by public water systems. Department of Health regulations establish limits for contaminants in bottled water which
must provide the same protection for public health.
Is our water system meeting other rules that govern our operations?
The Missouri Department of Natural Resources regulates our water system and requires us to test our water on a regular basis to ensure it's safety. Our
system has been assigned the identification number MO4010279 for the purposes of tracking our test results. Last year, we tested for a variety of
contaminants. The detectable results of these tests are on the following pages of this report. Any violations of state requirements or standards will be
further explained later in this report.
How might I become actively involved?
If you would like to observe the decision-making process that affect drinking water quality or if you have any further questions about your drinking water
report, please call us at 573-431-2280 to inquire about scheduled meetings or contact persons.
Do I need to take any special precautions?
Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons
with cancer undergoing chemotherapy, persons who have undergone organ trans-plants, people with HIV/AIDS or other immune system disorders,
some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care
providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are
available from the Safe Drinking Water Hotline (800-426-4791).

Contaminants Report
Definitions:
MCLG: Maximum Contaminant Level Goal, or the level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.
MCL: Maximum Contaminant Level, or the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available
treatment technology.
AL: Action Level, or the concentration of a contaminant which, when exceeded, triggers treatment or other requirements which a water system must follow..
TT: Treatment Technique, or a required process intended to reduce the level of a contaminant in drinking water.
90th percentile: For lead and Copper testing. 10% of test results are above this level and 90% are below this level.
Level Found: is the average of all test results for a particular contaminant.
Range of Detections: Shows the lowest and highest levels found during a testing period, if only one sample was taken, then this number equals the Level Found .
MRLDG: Maximum Residual Disinfectant Level Goal, or the level of a drinking water disinfectant below which there is no known or expected risk to health.
MRDL: Maximum Residual Disinfectant Level, or the highest level of a disinfectant allowed in drinking water.
Abbreviations:
PPB: parts per billion or micrograms per liter.
ppm: parts per million or milligrams per liter.
n/a: not applicable.
NTU: Nephelometric Turbidity Unit, used to measure cloudiness in drinking water.
MFL: million fibers per liter, used to measure asbestos concentration.
nd: not detectable at testing limits.
The state has reduced monitoring requirements for certain contaminants to less often than once per year because the concentrations of these contaminants are not expected to vary
significantly from year to year. Records with a sample year more than one year old are still considered representative.

to assist the EPA in determining the occurance of unregulated contaminants in drinking water and whether future regulation is warranted. Information on all
the contaminants that were monitored for, whether regulated or unregulated, can be obtained from this water system or the Department of Natural Resources.
